8 Claims.

This invention relates to a stop or check devioefor springdriven roller window shades.

Heretofore there has been no simple and effective stop or check for window shades mounted on spring driven rollers. When raising a shade which had no cord, but was provided with a tassel, there was the possibility of the roller overrunning itselfthat is spinning after the shade was fully rolled, with a consequent loss of spring tension and possible injury to the tassel when made of brittle material such as glass. To restore the spring tension it was necessary to remove the shade roller from its supports and rewind.

To avoid such an annoyance, I have devised a stop, formed preferably of rubber or any soft or resilient material which is positioned at the lower partof the shade and which abutsagainst the window frame lintel when the shade is raised, thus blocking any further winding of the roller.

My invention will be made clear by reference to the accompanying drawing which is for illustrative purposes only and are not to be understood as limiting the scope of my invention as the same may be employed in various forms and embodiments.

In the drawing:

Fig. 1 is a perspective view of a window shade and my invention applied thereto;

Fig. 2 is a sectional view of the shade roller when the shade is fully raised;

Fig. 3 is a perspective view of a shade stop embodying my invention;

Fig. 4 is a longitudinal section of the stop, and

Fig. 5 is a longitudinal section of a modified form of stop.

In these figures a shade roller with a shade 12 is positioned in a window frame 14, as is customary, slightly below the window frame lintel 16. The shade may be reinforced by a slat or bar' 18 in a loop of shade material as at 20. A hole 22 may be provided through the middle of the shade bar and its covering.

The stop 24: may include a slot 26 into which the shade bar is positioned, a half spherical or knob-like portion 28, for the front of the shade, an elongated generally conical check portion 30 for the back of the shade and a yoke or connecting member 32 which latter may pass under the shade bar as shown. The knob-like portion 28 holds the bar away from the balance of the shade when in rolled position and therefore check portion 30 does not have to be as long as otherwise. Preferably portions 28 and 30 will be so formed that their longitudinal axis will be alined with the hole of the shade bar and so that they tend to balance eachother in a, measure. On this-longitudinal axis a hole 33 is formedin knob'pq tionflfiand, a

well 34 is formed in the elongated cone 30.

A bushing 36 is placed in hole 83 and may be secured therein from displacement by an annular ribbing 38. A threaded bushing 39 may be positioned by means of the annular flange 40 in well 34 preferably some distance from the entrance thereof to allow for a clamping cushion as at 41. A screw 42 connects portions 28 and 30 of the stop, holds them in proper relative position, and may run as shown through the hole 22 of the shade bar It will be noted that the screw and bushings stiifen the stop which is preferably formed of rubber or other resilient or soft material. A shade cord and tassel 44 may be looped over the yoke 32, or secured thereto by a pin 46 as shown.

The elongated conical portion 30 should obviously be slightly longer than the distance between the shade when rolled up and the lintel. Knob-like portion 28 both tends to balance portion 30 and to raise the shade bar from the balance of the shade when the latter is rolled; When the shade is raised, portion 30 abuts against the lintel and blocks any spinning of the roller and shade. However, the shade may be fully raised with the stop in position.

In the modification shown in Fig. 5 the sides of slot 27 may be tapered as shown to fit a tapered shade bar. The stopis moulded with a longitudinal hole 4.3 which is enlarged at the outer end of check portion 31 to take a nut 50. The sides of slot 27 may be recessed as at 52 where it crosses hole 43 in order to fit over any eyelet which may be fixed in the shade bar hole 22.

' Knob-like portion 29 at its outer end is provided with a beveled recess 54 in which a beveled eyelet or collar 56 is slipped. Elongated bolt 58 connects portions 29 and 31. An eyelet 60 may be positioned in hole 61 of yoke 35 to take the tassel cord.

I have disclosed and described what I regard as the most feasible embodiments of my invention, which latter may be formed in various embodiments and which essentially comprises a resilient stop upon a shade or rolled material which I will ab-ut against aframe member, and the appended claims include such embodiments.

What I claim is: l. A device of the type described comprising, a knob-like portion to go on the front of a I to be positioned to the rear of the bottom of the v core, and a connecting member adapted to pass through the window-shade bar and hold said other two members in proper relative position.

2. A resilient stop for a spring driven roller shade adapted to be mounted on the shade bar of such shade comprising a knob-like portion in front of said shade bar and a check portion in the rear of said bar, and a connecting member for said portions.

3. For use in a window frame, a resilient stop for spring driven roller shades which includes an elongated generally conical member adapted shade and adapted to abut against the lintel of said frame when the shade is rolled up.

4. For use with a frame, a shade 'adaptedto be wound on a spring roller, a resilient stop positioned upon said shade adapted to abut against said frame when saidshade is rolled.

i 5. A rubber stop for spring driven shades adapted to bepositioned upon the shade bar which includes a knob-like member in-front of said shade bar, a check member to the rear of saidshade and means for connecting said members, said members tending to balance one another.

6. A stop as described in claim 5 which further includes a connective yoke member adapted to run under said shade bar.

7. A resilient stop for spring driven shades adapted to be positioned upon the shade bar which includes a member for the front of the shade bar adapted to raise the bar from the rest of the shade when the latter isrolled, a member for the rear of the shade bar adapted toabut against the window frame, and means for connecting said members.

8. In a resilient stop for spring driven window shades adapted to be fastened to a bar at the end of the shade, a projection adapted to engage HERBERT H. ILLCH.
